SUMMARY Glucose‐6‐phosphate dehydrogenase, hexokinase and phosphoglucose‐isomerase extracted from roots of Pinus sylvestris L. or Fagus orientalis Lipsky were not inhibited by mannitol at concentrations up to 0.5 M in contrast to previous reports for these enzymes from Fagus sylvatica L. The K m ‐values for the carbohydrate substrates were the same in the presence or absence of mannitol (50 mM).
